Capacitive Reactance (Xc) vs Capacitance

Fórmula

## Capacitive Reactance **Xc = 1 / (2 x pi x f x C)** Reactance decreases with frequency: capacitors pass high frequencies and block low frequencies (DC).

Ejemplo Resuelto

10 uF capacitor at 1 kHz.

  1. 01C = 10 uF = 0.00001 F
  2. 02Xc = 1 / (2 x pi x 1000 x 0.00001)
  3. 03Xc = 1 / 0.06283 = 15.92 ohms

Preguntas Frecuentes

Why does reactance decrease with frequency?

At higher frequencies the capacitor charges/discharges faster, presenting less opposition to current flow.

Is reactance the same as resistance?

No. Reactance causes a 90-degree phase shift between voltage and current. It does not dissipate power.

What about ESR?

Real capacitors have equivalent series resistance (ESR) that adds to the impedance and does dissipate power.
